IMPROVEMENT IN CHURNS.

Specification forming part of Letters Patent No. 168, 123, dated September 28, 1875; application filed August 11, 1875. v

part of this specification.

My invention relates to an improvement in Y churns; and it consists in the arrangement and construction of parts that will be more fully described hereafter. v

The accompanyingfdrawings represent my invention.

. a represents the churn, in which the milk is placed, and which is surrounded by a water jacket or space, b, inthe usual manner. The

water is poured` into this space through the openings at c, and is drawn 0E at d when no longer desired. The bottom of the churn being raised up above the bottom of a waterjacket, as shown, so that the water can act on the bottom as well as the sides of the churn, there are a number of radial supports, c, placed under the bottom of the churn, so as to support the weight of milk in the churn. I These supports do not quite meet in thecenter, so as to leave a space-through which the water can readily flow in being drawn off. In one side there is made an elongated opening,- o, in the water-jacket, which iS opened and closed by a slide or cover, g,so as to exclude the air I from the thermometer h, which is placed there- 1n. The top, bottom, and sides of this opening o are closed by strips of wood i, that are `sufficiently thick to not only prevent the wa- Having thus described my invention, I4

claim- 1. The chamber o, made wholly within the water-chamber b, and provided with the slide g, in combination with the thermometer h and dividing-strips of wood i, whereby the thermometer is protected both from the heat of the water in the chamber b and the outside air, substantially as shown and described.

2. The braces or supports c, placed radially under the bottom of the churn, and having spaces between them for the water to ow freely between, as set forth. Y

In testimony that I claim the foregoing I have hereunto set my hand this 28th day of July, 1875.
